Title (EN) MEMORY DEVICE
(FR) MEMOIRE
Abstract: front page image
(EN)When it is judged that a read request is made, it is judged whether or not the designated read address is in a specific area. If the address is in the specific area, the processing is ended, that is, the processing is ended without read. If the address is not in the specific area, data at the designated address of a memory is read, and the read data is sent to a host device. After the read, for example, the read address stored in a register is written in the specific area. In the specific area, the address from which data is read is additionally recorded. Thus, the data that has been read cannot be accessed by the host device.
(FR)L'invention concerne l'évaluation d'une demande de lecture visant à déterminer si l'adresse de lecture désignée se trouve dans une zone spécifique. Si tel est le cas, le traitement prend fin, sans lecture. Dans le cas contraire, les données de l'adresse désignée d'une mémoire sont lues et transmises à un dispositif hôte. Après la lecture, par exemple, l'adresse de lecture enregistrée dans un registre est écrite dans la zone spécifique, où l'on enregistre également ladite adresse. Ainsi, le dispositif hôte ne peut pas accéder aux données qui ont été lues.
